Patent FR-2345398-A1 (FR)
Title: Rotary surface aerator for biological water treatment - with internal blades and external Archimedean screw circulator
Inventor: HAMEL RAYMOND
IPC: C02F3/18
Filed: 1976-03-24
Abstract: Rotary surface aerator, for the oxygenation of waste water and sewage in a biological treatment tank, consists of a drum with a horizontal axis; internal blades are fixed to the shaft to create turbulence and a discharging spiral is provided at the outlet end. An Archimedean screw, coaxial with the drum, is fixed to the outside surface of the latter. The blades consist of thin metallic plates fixed tangentially to the shaft; their length is such that they are nearly flush with the drum without actually touching. Their inclination is variable so that the circulation of the water can be adjusted as a function of the rotational speed of the drum. The aerator is immersed in the water so that its shaft is slightly above the water level; as the drum rotates the blades lift the water on the ascending side and allow it to fall on the other in the form of fien droplets. The oxygenated water is drawn out the spiral while the Archimedean screw serves to circulate the upper and lower layers of water. The aerator is flexible in use and can be employed for circular, annular and rectangular oxygenation tanks. It is more partic. useful for those of the channel type.

Title: Recovering a submarine by manipulation from a ship - by lifting from a submerged position at a specific rate, greater than that of the rising of the swell
Inventor: MARQUINEZ JEAN-PIERRE
IPC: B63B27/16
Filed: 1976-04-02
Abstract: A small submarine is recovered from the sea by submerging the submarine so that it is in a calm zone at a depth 3-5 m below the mean surface of the sea, attaching a lifting cable to it, maintaining the cable at a constant tension, drawing up the submarine at a lifting speed greater than that of the rising of the swell of the sea and depositing it on the deck of a ship. The submarine is brought to the surface to attack the cable and a guide cable is passed from a winch through a channel in a grab attached to the lifting cable. The grab is slid along the guide cable up to the submarine and bolted to it. The guide cable is freed and wound on to its winch. The submarine can be recoverd from aft of the ship or from the side, while the ship is under way or stopped. Movements of the submarine while it is suspended are limited. People, e.g. divers, other than the crews of the ship or the submarine are not needed and the operations are under the control of one man.

Title: Solid tantalum capacitor mfr. - using two=stage anodic oxidn. of sintered anodes to lower residual current in capacitors (NL 11.7.78)
Inventor: MOULIN MICHELE
IPC: C25D11/26
Filed: 1977-01-07
Abstract: Sintered tantalum anodes are anodically oxidised for capacitors with a solid electrolyte. In a first stage (a) the anodic oxidn. is stopped when part of the thickness of the oxide layer is reached. The anodes are then washed in acid, followed by a neutralising rinse, before the anodic oxidn. is completed in a second stage (b). Stage (b) is pref. started at the same voltage as that existing at the end of stage (a). In stage (a) the max current is pref. applied to loosely connected anodes until the voltage has stabilised at the highest value plus-or-minus 10%; and the anodes are mounted on a belt for stage (b), which starts at max. current. The acid bath for washing is pref. an aq. soln. of HNO3, H2SO4 and HF but two acid solns. may be used with different concn., followed by neutralising rinse, then washing in de-ionised water. As compared with conventional Ta capacitors, the residual current is much less and is at a consistently low value.
